Top Level Elements

The top element of any common reference element or arrangement is a world element, specific to the type of common reference element or type of arrangement. The top elements are:

• SPMSW for space arrangements

• FNCAW for area arrangements

• FNCCW for curve arrangements

• SSOWLD for surfaces

• CURWLD for curves

• PNTWLD for points

The different world elements can be created using the functions under Worlds in the Create group of the General ribbon tab.

The specialization of arrangements, setting up the attribute collections for a specific pre-defined purpose is done by defining the type of arrangement. This is done on the world element, using the Property grid.
